For anyone with a LWB version :As it turns out the LWB connect door removal is quite different and removing the slider as outlined in this video doesn't seem to work. However what was a much easier way of removing the door is just undoing the little circlip and removing the pin from the middle sliding mechanism, then you only need to undo the bolts on the top and bottom sliding mechanisms...door comes off easy peasy. I used a small bike lift to support the door and removed it all solo with no issues 😎

Bit of a long story... I myself was driving about with a strong draft after the porthole I installed flew out of it's hole on the A9. Since replaced and firmly in place, but I figured after that incident that perhaps I ought to leave the sequel of this video to the imagination. It's a bit like the struggle of the second album...
